Astera Labs, a key connectivity player in AI data centers, is trading 6.2% up today at $9.24. The rally is primarily driven by its official inclusion in the Nasdaq-100 Index, effective today, June 22, 2026, which is prompting passive buying from index-tracking funds. This builds on prior market enthusiasm from its Q1 2026 results, which reported a 93% year-over-year revenue jump, reinforcing its strong position in the AI infrastructure build-out.
